我是铁杆的新手，并试图弄清楚我做了什么搞砸了。我做了rails并查看了我的主页并得到了错误

sample_app /应用/视图/布局/ _header.html.erb

undefined local variable or method `help_path'

<nav>
           <ul class="nav pull-right">
             <li><%= link_to "Home",    root_path %></li>
             <li><%= link_to "Help",    help_path %></li>
             <li><%= link_to "Sign in", '#' %></li>
           </ul>
         </nav>

  <div class="navbar-inner">
    <div class="container">
      <%= link_to "sample app", root_path, id: "logo" %>
      <nav>
        <ul class="nav pull-right">
          <li><%= link_to "Home",    root_path %></li>
          <li><%= link_to "Help",    help_path %></li>
